- such a flow-deflecting device can also be provided in the region of the fixed rated-current contact 104, in order to redirect the quenching gas flowing out in its direction there.
- FIG. 2 shows a cross section through the flow-deflecting device 1 and the encapsulating 101.
- the flow deflecting device 1 has a substantially circular cross section. There are several inside Tabs 4a, b, c, d, e, f arranged. The tabs 4a, b, c, d, e, f serve both the mechanical support of the flow deflecting device 1 at the interrupter unit 102 as well as the electrical contacting of the interrupter unit 102.
